+.B  -d, --delay-create-ostobj [on | off]
+Delay to create the lost OST-object for dangling LOV EA until orphan OST-objects
+handled: 'off' (default) or 'on'. If both "--create-ostobj" and the delay option
+are 'on', then the LFSCK will NOT create the OST-object to repair dangling LOV
+EA unless all the OST-objects have been handled. It can avoid reparing dangling
+LOV EA incorrectly because of LOV EA corruption. The side-effect is that as long
+as one OST does not join the layout LFSCK or fail to complete the scanning, then
+reparing dangling LOV EA will be skipped. For a large system with a lot of OSTs,
+such condition may be a bit strict. The default value is 'off'.
